I am surprised to be the first reviewer of this important book. I suspected this to be lipsticked version of the author's book from 1994, but it is actually extensively updated. Although Usability Engineering has its problems, its ability to produce arguments that decision-makers listen to is crucial. Today, usability simply to seldom make it to the executive's desk. More usabiliity professionals and academics armed with arguments from this book can change that. I am using it in my research and teaching.
It lies in the nature of research-based book like this one that many data is a few years old, but that is the price you have to pay for a critical-minded compilation of facts; the alternative is to rely on intuition and word-of-mouth within your own company and network.
